Great post from Ken!

To add to that, I would say:

Until you find your feet again, start each day with a really high fat, low carb meal, plenty of calories.

If you can't face giving up everything all at once, pick the thing that is your biggest problem - for me it was sugar, and make that your 'rule number one' as Ken says. Then once you have 90 days without that thing, add something else. I call this a stepped approach, and it was what I had to do.

At the beginning, forget calories and if your eating is really out of control, forget carbs, just pick the thing you have the most problem with, whether it be sugar, grains etc and don't have it for 90 days. But as Ken says, always follow rule number one.
